C4 alkylation to produce clean gasoline solid acid catalyst
Product features and scope of use
This technology has developed a solid acid catalyst based on molecular sieve technology, which can be applied to the C4 alkylation process. The isobutane and olefin in the mixed C4 are converted into gasoline under the action of the catalyst. The alkane produced by this method Base gasoline has high octane number, low sensitivity, ideal volatility and clean combustibility. Compared with the acid catalysts used in traditional alkylation units which are sulfuric acid and hydrofluoric acid, solid acid catalysts have low risk, and do not need to dispose of waste acid solutions and other good environmental performance, and can replace traditional alkylation acid catalysts.
